Maximum Contact Pressure for Heavily Loaded Bearings

materials' operating limits. It is common to use the average contact pressure, the applied load over the projected area (P=L/(D*W). However this severely underestimates the actual maximum pressure on the system. Alternatively, one can calculate the Hertzian stress between the two cylindrical contact surfaces. This provides an accurate value

Bolt Torque & Preload Calculator | MechaniCalc

Due to preload uncertainty, the actual preload applied to the bolt may be more or less than the nominal value. Due to preload relaxation, there will be some loss in the preload after the joint is installed. The maximum value of preload accounts for the preload uncertainty, and is calculated as: F PL.max = (1 + % uncrt ) · F PL.nom =. 533.0 lbf.
